Hoda- IMPROVEMENT IN .HAY-STACKERS.

The Schedule referred to in these Lettera Patent and making of the same.

To all whom it may concern:

Be it known that I, T. N. BUNNELL, of Reynolds,

.in the State of Indiana, have invented a new and useful Improvement .inHay-Staekers and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, and letters of reference marked thereon, making apart of this specification, in which- FigureJ is a side elevation, and

Figure 2, a plan view.

To enable those skilled in theart to make and use my invention, I nowproceed to describe its construction and operation.

Similar letters in the drawings refer to like parts.

This invention consists of a vertical frame-work, mounted in a kind ofsledge, suited for transportation, having a bar pivoted crosswiseof itsupperend, from which bar projects upward an iron bolt that forms thepivot, upon which a long lever may be moved fromI side to side, and thatso connects the lever with the said'pivoted bar as to make of the lattera fulcrnm for the former in its vertical movements, said lever havingsheaves at, its ends, over which the hay-fork rope passes, and beingmovable both vertically and laterally so as to both raise hay from theeld and swing it sidewise upon a stack; and being controlled in itslateral movements by a stay-rod, connected at one end `with the ropethat retains the lever at its but, and

pivoted at the other end to the said vertical framework.

Y In the drawings---` A is the frame-Work, consisting mainly of a pairof vertical posts, a. a, stepped each in a shoe, A', the two shoes beingconnected by cross-pieces, so as to form a sledge suitable fortransportation.

The posts a a are so stayed and braced that the t frame-work is madesuiiciently strong.

Grosswise of the frame-work is a bar, B, having its ends pivoted in thetops ofthe posts a.

Upon 4the upper side of the bar B rests a long lever,

O, a bolt connecting these two parts in such a manner that the levermaybe vibrated up and down upon the bar as a fnlcrum, and at the sametime swung to and fro upon the bolt, as a pivot.

In the ends ofthe lever are sheaves, c c', over which the h. y-fork ropec" passes, proceeding from 'the latter sheave through the block d,fastened near one corner of the sledge. horse.

The lever C has a short post, G', projecting from its upper side, inthetop of which is a sbeave, over which the rope c runs, and through thepost extends the iron brace e that stifens the lever.

A rope, D, connects the but of the lever with one corner of the Sledge,in order tol check the leverf'rom rising too high under the weight ofthe hay, and lregulates the lateral motion of the lever.

A stay, d', pivoted at one end to the brace of the vertical frame-work,slides at the other end upon the rope D, and in proportion as the saidend of the stay is lower or higher upon the rope, the lateral play ofthe lever is greater or less.

WVhen the hay-fork receives its load, the horse is started, and the forkraised vertically till it, or a stop on the rope, strikes the end of thelever. The latter is then carried along with the fork in a slantingdirection, so as to swing the hay over the stack, where it is dropped:

On backing up the horse, the parts assume automatically their properpositions.

IVhat I claim as new, and desire to secure by Letters Patent, is-

' The frame-work A, combined with the pivoted bar B, the lever O, ropeD, and stay d', in the manner and for the purpose set forth.
